I think the introduction should discuss why it is not possible to push the

You can't replace an entire zone with a CNAME if it has subdomains. ANAME
records are not just for zone apexes. There are lots of other cases where
address records need a different alias target from MX records, or NAPTR
records, etc.
Sure, but the document should list that.
FWIW, I think the real problem is that it is perceived as cheaper to
upgrade DNS servers than to support CNAME records in the provisioning
infrastructure.
Thanks,
